Cooig',"a, 'citizen of the-Univ d,"St-at'es, residayne State f ',c rtainnew and useful Imp1;(nementsl irrY .vesfQrMOtors, et' whiclith'efollowin'g'is a 'specilication This invention rela-tes It()y 'n the,means for admitting fluid! to andjegliausting it. from a motor and haspalticlar reference to a gasolene. engine ,Oiftie explosive v t-ype, but

' it willbe understondthae some'of the fea- 4 gasolene engine. as supplyand exhaustturesfc the inventionare useful in other relations.,

I t-h'as been 'my object {td'soconstruct and arrange. the. i'nletgaiid,.exhaust valves of a lh?{ fnot;. only. prpperly 'thematerial but to runeasilyandsmoothly without noise or hammering., To this endl; make use`of balanced rotary valt/es yhereiliafter described. The v'novel vfeainires yof the invention will `-be apparentfromthe followingdescription taken in 'connection withthe'drawings.

A Inthe. 'drawingsLFigure 1 is 'a vertical section through/v. engine'cylinder having my vvalve applied l HeretmgFig. 2 is averti'ca'l.section taken on 'the line 2-2 of Fig. 1. i l. fi' y In these drawingsI, have shown an Ordinary' engine cylinder`- llhaving the Water jacletgland in which the piston 3 works, this piston being connected in theusual way to' a drive shaft by. the piston rod .4. Below thecylinder-head 5. I place .in the side wall ot' the cylinder', valvesockets' 6 and 7 providing seats in the housing which are arrangeddiametrically opposite each otherl and which preferably taper outwardlyits shown so as to 'furnish' conical bearings.

' The bearing 8, having therein the socket 7,

is made removable being preferably circular in crosssection and adaptedto slidev ipv t- 'C end of the valve member. from turning by a pin9inserted through the top of the casing with its inner end entering alongitudinal slot QT so as to act as'a key and prevent the turning ofthe bearing 8 while permitting its longitudinal movement. The pin 9 ispreferably provided with a central passageway 23, for oil and thispassagewagi7 may be connected at iftsfmiter end in any suitablev way toan Oil supply. The oil may pass through a pasjrangement of the sagew'ay.24 so as to lubricate the valve plug 121:, and atthe 'other end of thevalve' member thereis a passageway 25 for`0il which passageway or lductentends through the socket, (L A spring .l0 cngagesv. the outer ward,-this spring being held by. a ring 11 having screw-tln'eaded connectionwith the casing. ofvthe cylinder. A. valve melnberfll having on its endsthe tapering valve plugs V-or .seats 13 and 14 extends across Vthe upperend. ofthecylinder with its valve plugs fit.- tifng in the ,sockets Gand 7. These valve seats 13, 14 are tapering or inclined relatively tothe axisot the valve member 12. T his valve member is preferablycylindrical in, form with 4t-he'exception of its taperfaceof :thebearing 8 tending to push itining end, and passages 15, 16. are formedVtherein at ythe opposite ends communicating with the interior of thecylinder. -Each of these passages l5, 1,6, 1s a port connecting passage, extending from `the explosion cham.- ber exposed passage medlallysurrounding the valve member to communicate respectively .with the inletport. 17 and the exhaust,y port 1S. The passagewayl communicates wltlithe inlet pipe ,17 throughan openingl in its side, and in lthe same .waythe passage 16 communicates with the exhaust, pipe l 8. The openingbetween `the .passagel and the inlet ,pipe is o'fcourse arrange ,at-adifferentpoirit on `the circumference of the; valv'emember'l from that,of theo ening' leading from. the passageway 16 tot e exhaust, 18 4sothat the inlet aiid-ehaust to' the cylinder will be .properly timed! Itis' not necessary to describe the relative arl inlets and Outlets sincethis will/be understood by thosskilled'n the-art'. s

The valve member maybe provided with the packing grooves '26 as shown orany other suitable form of packing. A screw plug 19 closes an opening inthe casingat on'evend of the valve member and'on the other end there isan extension 20 to which is keyed a. sprocket'wheel 21 or other means'fOr driving the valve member. It will be understood that the wheel 21 isdriven 'from the main shaft of the engine so as to prop-1 crly time theadmission and exhaust of fluid from' the engine by the valve: member 12.

Since the valve member 12issymrnetrical- Y in cross section and inlongitudinal section,

i' are duplicates of each other, any pressure within the engine cylinderupon the valve member Willbe equal in all vdirect-ions and consequentlyit will be balanced. Any pressure tending to force one valve plugagainst its seat Will be. eounteracted by the tendency to force theopposite valve plug against its seatsince the two are connected togetherand have equal projected areas forming pressure balanced faces. Sincethe 'valve operates by continuous rotary motion and is balanced asdescribed it will Work easily and Without noise to efficiently admit.and exhaust the material. In order to more effectively admit thematerial to the upper end of the cylinder .ll preferably provide thevalve member l2 with a passageway 22 leading into the passageway 15.

Having thus described the invention what I claim as new and desire tosecure by Letters-Patent is:

l. in internal combustion engine rotary valve provided with an axia lyextending inlc'tport and extending therefrom an axially extendingexhaustport, said valve being tapered, and housing means for said valveembodying opposing tapering seats and means for adjusting one of saidseats toward and from the valve.

:2. The combination with an engine cylinder of a cylindrical valvemember lextending across said cylinder having tapering ends extendingbeyond the inner walls of said cylinder and provided with passagescommunicating vvith said cylinder, tapering valve sockets in the Wallsof said cylinder in which the tapering ends of said valve member fitland adjustable means for removing one of said sockets to permittheinsertion of the valve member.

3. ln a device of the class described the combination with an enginecylinder having outwardly tapering valve sockets in its wall in line onopposite sides, of rotary valve plugs fitting said sockets and havingpas- "sages communicating with the interior of said cyllnder, the saidplugs being connect- Lief/,eos

led vvhereby the pressure with@ thet cyliin;

ting said sockets and having similar pas-,p

sageways to the interior of said cylinder,

and spring pressed means for relatively adjustingene of said plugs andits socket to automatically maintain a tight joint.

5. Ain internal combustion engine rotary valve provided ivi th an inletportl and an exhaust port, said valve being smaller near its outer end,there being a port connecting passage in said valve providing pressurebalanced faces,and housing means for said valve embodying' a taperingseat, said housing having an explosion chamber exposed passage incommunication with the valve passage. l

(i. An internal combustion engine rot-ary valve provided with an axiallyextending passage having a radially extending port, said passageincluding pressure balanced opposing faces, and a valve housing hatingan explosion chamber exposed passage in communication With said faces,said housing having a seat for the valve tapering inward as `thedistance from the communication between the housing and valve passagesincreases.

In testimony whereof 4I atiix ,my signature in presence of twowitnesses.
